What Is Spalled Concrete
Spalled concrete ultimately boils down to surface breakage. It is the cracking of concrete usually extending to the upper layers of the reinforced steel. Affecting surfaces starting from bridges, tanks, multi-story buildings, and much more, it leaves the concrete surface patchy and hollowed – exposing the elements underneath. If construction solutions are not applied at the earliest, it could lead to the widening of cracks making the structure unstable. Moreover, spalled concrete takes away from the aesthetics of the building, making it unattractive and aged.
Causes For Breakage and Spalling Of Concrete
- Inferior quality of concrete
- Improper concrete finishing techniques
- Bond failure in two-course construction due to shrinkage
- Corrosion due to weather, etc.
- Freeze-thaw cycle
- Fire or extreme exposure to heat
